وَيَجْعَلُونَ لِلَّهِ الْبَنَاتِ سُبْحَانَهُ وَلَهُمْ مَا يَشْتَهُونَ
They assign daughters to God—glory be to Him—while claiming for themselves whatever they desire. (An-Nahl 16:57)
«سُبْحَانَهُ» interrupts the report with an expression of divine transcendence. The interruption shows that the false attribution is being rejected, not merely narrated without comment.
Benefit: the listener hears a declaration of God’s perfection at the very point the offensive claim is mentioned. The parenthetical phrase serves a distinct and immediate rhetorical purpose.
